REA03D0004-0100 Rev.1.00 Dec 25, 2006
Description
RNB4580 is dual bipolar low noise amplifiers designed for audio systems to improve tone control, audio pre-amplifier and industrial measurement tools. It also suitable for head phone amplifier at higher output current. This product features internal frequency compensation, low noise, low distortion, high gain and high bandwidth. It also can operate under dual power supply voltage up to 18 V or single power supply up to 36 V. The IC can be applied for the handy type set operational amplifier of general purpose in application of low voltage single supply type, which is properly biased of the input low voltage source.
